If your Web server should be visible from the internet you should do: - create a dynamic nameserver address, e.g. dnydns.org (but there are a lot of others. An example may be: yufan.dnsalias.org This address will be used from the internet to access your web server - configure your router (better) or the machine which hosts your web server (not so gut) to update the dynamic dns each time you get a new IP address from your provider. - configure your router to forward request on port 80 to your server. Forget about DMZ in your case - configure your web server to anser to the name you choosed in step 1, e.g. ServerName yufan.dnsalias.org If your Web server should be visible from your internal network, too: - configure your Web server to answer to a second name, too, which is used on your internel network, e.g. yufan.internal ServerAlias yufan.internal - Enable all your clients to find yufan.internal a) create an entry in /etc/hosts on each machine, eg. 192.168.x.y yufan.internal (windows has a correspondig location for the host file inside c:\windos, I yust don't remember the exact place) b) set up a full internal DNS If you have only up to about 10 machines on your internal network, it may be less work to use alternative a) Have fun Peter
